The Fundamental of Leaky wave Antenna

Abstract

The fundamental of leaky-wave antenna (LWAs) that have been compiled and published are presented in this paper. A leaky-wave antenna uses the guiding structural, which support the propagation of waves along the length of the structure. While the basic family of LWAs is dependent on the radiation of a propagative mode in a basic guiding structure (usually a waveguide of some sort), the radiation mechanism changes drastically from one sub-category to another. Such antennas either uniform or periodic appear in various characteristics and performances. The fundamental of the basic operating principles and physics, and discuss the design of types of LWA.
